Seriously why? Discuss.online has horrible moderation and open-signups, and Lemm.ee isn’t very much better. If lemmy.world and sh.itjust.works were completely nuked to avoid the moderation headache or risks from two large open servers, why aren’t lemm.ee and discuss.online banned as well?
lemm.ee is centralized in Cloudflare’s exclusive walled garden. I can’t speek for the admins but it’s antithetical to the purpose of the fedi to advocate for federation with centralized hosts.
And there are consequences. If an image is posted to Lemmy.world, sh.itjust.works, or discuss.online, those of us who are excluded from Cloudflare cannot see it. A non-CF node federating to a CF node creates a broken network.
